本研究使用不同情绪强度的面部表情照片，与健康对照组比较，考察了重度抑郁症患者对情绪刺激的辨别准确性。样本包括88名年龄在18-56岁，患有严重抑郁障碍(n=44)或没有精神疾病(n=44)的未确诊男性和女性受试者，他们判断了200张表情在10%(90%中性)到80%(细微差别)之间的面部图片的情绪。刺激以10%的增量呈现，以产生强度范围，每个强度呈现500毫秒的持续时间。与健康志愿者相比，抑郁症受试者对悲伤的面孔表现出非常好的识别准确率，但对其他情绪(例如，刺耳、惊讶和悲伤的表情)的识别准确率有所下降。随着对所有情绪强度的增加，两组人的识别准确率都有所提高。最后，随着抑郁症状的增加，悲伤面孔的识别准确率提高，但惊讶面孔的识别准确率下降。此外，抑郁的受试者表现出准确识别微妙面部表情的能力受损，这表明抑郁症状会影响情绪识别的准确性。
This study investigates the discrimination accuracy of emotional stimuli in subjects with major depression compared with healthy controls using photographs of facial expressions of varying emotional intensities. The sample included 88 unrnedicated male and female subjects, aged 18-56 years, with major depressive disorder (n = 44) or no psychiatric illness (n = 44), who judged the emotion of 200 facial pictures displaying an expression between 10% (90% neutral) and 80% (nuanced) emotion. Stimuli were presented in 10% increments to generate a range of intensities, each presented for a 500-ms duration. Compared with healthy volunteers, depressed subjects showed very good recognition accuracy for sad faces but impaired recognition accuracy for other emotions (e.g., harsh, surprise, and sad expressions) of subtle emotional intensity. Recognition accuracy improved for both groups as a function of increased intensity on all emotions. Finally, as depressive symptoms increased, recognition accuracy increased for sad faces, but decreased for surprised faces. Moreover, depressed subjects showed an impaired ability to accurately identify subtle facial expressions, indicating that depressive symptoms influence accuracy of emotional recognition.
